Answer:

q = 14

General Formulas and Concepts:

Order of Operations: BPEMDAS
Equality Properties
Complementary Angles: Angles that add up to 90°

Step-by-step explanation:

Step 1: Set up equation

The 2 angles must add up to 90°.

(4q - 5)° + 39° = 90°

Step 2: Solve for q

Combine like terms: 4q + 34 = 90
Subtract 34 on both sides: 4q = 56
Divide both sides by 4: q = 14

What is the solution set for the inequality 4 - 5g > 39?

katrin [286]

The solution set for the given inequality is $g > -7$

Given the following inequality:

$4 - 5g > 39$

<h3>What is an inequality?</h3>

An inequality can be defined as a mathematical relation that is typically used to compare two (2) integers or variables in an equation by illustrating any of the following:

Greater than (>).

Less than (<).

Greater than or equal to the other (≥).

Less than or equal to the other (≤).

Simplifying the inequality, we have:

$4 - 5g > 39\\\\5g > 4-39\\\\5g > -35\\\\g > -7$

Lewis walked 9/10 of a mile. His friend walked 2/5 of the way with him. How many miles did Lewis's friend walk with him?

iVinArrow [24]

Answer:

Lewis's friend walked with him 9/25 miles

Step-by-step explanation:

Given that

Lewis walked 9/10 of a mile

And His friend accompanied him on 2/5 of the way.

This is a simple question of fraction multiplication

The fraction 2/5 has to multiplied with the miles walked by lewis

$= \frac{2}{5} * \frac{9}{10}\\=\frac{9}{25}$

Hence,

Lewis's friend walked with him 9/25 miles

A car traveled 63 miles on 3 gallon of gas. What proportion can you set up to determine how many miles, m, the car can travel on

kari74 [83]

63/3= 21
So 21 miles per gallon of gas
To find 7, you multiply it by 7
21*7= 147
147 miles on 7 gallons of gas

What is the equation of the line, in point-slope form, that passes through the points (-1, 7) and (-2, 3)? A. y + 7 = -4(x - 1)

Nana76 [90]

In general point-point form, the equation for the line through (a,b) and (c,d) is

$(c-a)(y-b) = (d-b)(x-a)$

Here we have (a,b)=(-1,7) and (c,d)=(-2,3)

$(-2 - -1) (y - 7) = (3 - 7)(x - -1)$

$-1(y - 7) = -4(x+1)$

$y - 7 = 4 (x+1)$

Answer: Choice D
